Here's an interesting tidbit I wasn't previously aware of:

  "Mr. Kapuscinski is an amazingly courageous man," McKnight
  said, according to the law firm's news release. "He saw a
  company program out of sync with designated federal 
  guidelines and decided to make it right."

  He is also much richer. Under the False Claims Act, a 
  whistleblower who files a fraud complaint on behalf of the 
  government can share in the recovery. Kapuscinski will 
  receive a 15 percent share, or $19.2 million, according to 
  the law firm.
